Abstract

The utility model discloses a multifunctional device of solar water heater, which is characterized in that an upper water pipe and a lower water pipe are provided with air-breathing and exhausting apparatuses which are communicated with an air-exhausting pipe and an air-exhausting valve. The multifunctional device can be operated to absorb and drain the air in the upper and the lower pipes, then the air pressure in the pipes is lower, and the pipes can generate a siphon phenomenon to ensure that water is heat as soon as flowing out. When the hot water is short in use, the siphon phenomenon is stopped when the air-exhausting valve is opened, the water in the pipes can be fully drained and used. The utility model does not only save water resource but also provides an antifreeze effect when the pipes are empty. When hot water is used again, the instant heat effect can be achieved easily and quickly by operating the multifunctional device.

Among the figure 1, water tank, 2, delivery port, 3, evacuated tube, 4, upper and lower conduit, 5, mix water valve, 6, shower nozzle, 7, running water pipe, 8, air-breathing check-valves, 9, venting check valve, 10, piston, 11, piston rod, 12, handle, 13 exhaust-valve switching devices, 14, exhaust-valve, 15, air-breathing check-valves, 16, venting check valve, 17 air chambers, 18, valve body, 19, contact connects spool, and 20, seal, 21, resetting means

The specific embodiment:

In Fig. 1, one end of the delivery port 2 on water tank 1 top is inserted water tank bottom, delivery port 2 is communicated with evacuated tube 3 that makes progress and upper and lower conduit 4 respectively, or the outlet pipe of water tank bottom upwards to form the U type curved and be higher than the water tank horizontal plane and be communicated with evacuated tube and upper and lower conduit, the other end of evacuated tube 3 is communicated with exhaust-valve 14, the other end of upper and lower conduit 4 respectively with air-breathing check-

valves

8 and 15, mixing water valve 5 is communicated with, mixing water valve 5 is communicated with shower nozzle 6 and running water pipe 7 respectively, draw pushing handle 12 to connect piston rod 11 and piston 10, piston 10 seals to slide in air chamber 17 and moves back and forth, motion along with piston 10, it is the both sides of separation that air in the upper and lower conduit 4 successively enters in the air chamber 17 with piston 10 from air-breathing check-

valves

8 and 15, successively discharge again from venting check valve 9 and 16, air in the upper and lower conduit 4 are discharged the back air pressure pipeline that diminishes and are formed siphon, hot water in the water tank 1 flows in the upper and lower conduit 4 and promptly goes out instant heating, when not using hot water, open exhaust-valve 14 air and enter evacuated tube 3 back pipeline siphons termination, the Yu Shuike in the upper and lower conduit 4 all discharge utilization.

In Fig. 2, handle 12 and exhaust-valve switching device 13, piston rod 11 is connected with piston 10, draw-out handle 12 drives piston 10 and seal sliding motion in air chamber 17, it is a side of separation with piston 10 that air in the upper and lower conduit 4 enters air chamber 17 from air-breathing check-valves 8, advance handle 12, piston 10 seals sliding motion in air chamber 17, when compressed air backs down 9 discharges of exhaust valve last time, it is the opposite side of separation with piston 10 that upper and lower conduit 4 interior air enter air chamber from air-breathing check-valves 15 again, piston 10 moves back and forth a stroke, in air chamber 17 be that the both sides of separating have formed breathing process twice with the piston, air pressure diminished after this discharged upper and lower conduit 4 interior air fast, pipeline forms siphon and promptly goes out instant heating, and this form also makes device volume reduce, and capacity increases.Described air-breathing check-valves and venting check valve are similar to check valve.

When using hot water to finish soon, moving handle 12 connection exhaust-valve switching devices 13 press contact connection spool 19 and open exhaust-valve 14, exhaust-valve switching device 13 is to have the briquetting of projection to fixedly connected with handle 12 or be made as one, can be designed to ellipse, fan-shaped, other pattern such as cam, exhaust-valve 14 is opened the back air and is entered evacuated tube 3 pipeline siphons termination, moving handle 12 stops to press exhaust-valve 14 and closes, exhaust-valve 14 connects spool 19 by contact in the valve body 18, seal 20, resetting means 21, as spring, play pad, gravity reduction etc., exhaust-valve 14 can be designed to gate valve, ball valve or multiple on-off mode such as end, exhaust-valve 14 can be provided with separately, but on-off mode hand switch or other various ways, exhaust-valve 14 is opened the back air and is entered evacuated tube 3, pipeline goes out to inhale to be ended, and the Yu Shuike in the upper and lower conduit 4 all discharges utilization simultaneously, when reusing, draw pushing handle to repeat described process, pipeline forms siphon and promptly goes out instant heating.
